Therefore put on the full armor of God, so that when the day of evil comes, you may be able to stand your ground, and after you have done everything, to stand.
(Ephesians 6:13 (NIV))

Armor is something that is thought of as protection, as something impenetrable. In the physical world, armor is often associated with metal and is imposing in nature. In the spiritual world, armor is not something that you wear, but something that you carry. You carry it in your hands and in your heart. This armor is the Word of God and it is a strong foundation on which to build everything that you do. The strength and protection that you receive from this armor comes from fully knowing that God always keeps His promises. He always protects His children. It is this knowledge, and the faith to hold on to this knowledge no matter the circumstances, that is the strongest armor that has ever been created.

All throughout history, men in armor have fought bravely and valiantly for something that they believed in. Even today, men in armor such military vehicles continue this tradition. They are fighting for earthly causes. How can we, when equipped to battle in the spiritual realm with God as our commanding officer and protector, not fully train to be part of the battle? We must keep our armor ready for we do not know what tomorrow may bring.
